/* ===========================================================
   MTL Electric - Our Work gallery (/our-work)
   Implements the "Our Work Page" design (Claude Design).

   Loaded after css/shared.css and css/service.css (design
   tokens, base reset, buttons, .svc-crumbs, .svc-eyebrow and
   the .svc-cta closing band). The tiles, category chips and
   photo count are generated by build.js from content/work.json.
